Relationship between depression and movement quality in normal young adults

[Purpose] Somatic symptoms, such as hyposomnia and anorexia, can affect depression and result in decreased movement quality; however, the relationship between movement quality and somatic symptoms is unclear. The present study investigated the characteristics of this relationship using observable posture and movements. [Participants and Methods] Twenty healthy young adults (mean age 20.9 ± 0.4 years) participated in the study. First, we administered the Self-rating Depression Scale questionnaire to the participants. Second, a qualified physical therapist assessed the movement quality of the volunteers using the Body Awareness Rating Scale-Movement Quality and Experience. We classified the participants into high- and low-score groups based on their Self-rating Depression Scale scores and then analyzed the Body Awareness Rating Scale-Movement Quality and Experience scores in both groups. [Results] There was a significant difference in the movement quality between the Self-rating Depression Scale high- and low-score groups. The Self-rating Depression Scale total score ranged from 20 to 80, with higher scores indicating a greater severity of depression. The low-score group had higher scores for the Body Awareness Rating Scale-Movement Quality and Experience than the high-score group in all items. [Conclusion] The present study showed that movement quality was related to symptoms of depression, thereby suggesting that early detection and treatment interventions for depression are possible by an assessment of movement quality.
